"The patient's family gathered to..." joke

The patient's family gathered to hear what the specialists had to
say. "Things don't look good." The only chance is a brain transplant. This
is an experimental procedure. It might work, but the bad news is that brains
are very expensive, and you will have to pay the costs yourselves."
"Well, how much does a brain cost?" asked the relatives.
"For a male brain, $500,000. For a female brain, $200,000."
Some of the younger male relatives tried to look shocked, but all the
men nodded because they thought they understood. A few actually smirked. But
the patient's daughter was unsatisfied and asked, "Why the difference in
price between male brains and female brains?"
"A standard pricing practice," said the head of the team.
"Women's brains have to be marked down because they have actually
been used."
